To all whom it may concern:

Be it known that '1, WILLIAM THOMAS SNowDnN, a citizen, ofthe United States of America, and resident of Toronto, county of Jefferson, and State of Ohio, have invented eertain new and useful-Improvements in Combustionlaeilitating Devices for Internal-Combostion Ilngines, of which the following is a specification.

This invention relates broadly to fuel economizers for internal combustion engines, and more particularly to an apparatus for facilitating the combustion of gases in sueh engines.

The primary object of the invention is to provide an apparatus whereby an emulsionor mixture of mineral oil and \a er may be eontrollably supplied .to the manifold of an inlernal combustion engine for mixing with the vaporized fuel which is drawn through said manifold in the usual manner to produee explosive eharges whieh are more readily eom mslible'and whi h consequently, possess materially .iiurreasetb potential energy.

A further object is to provide an apparatus of the eharaeter mentioned designed for the intrmluetion in an engine of a (0mbustion-laeilitating fluid or mixture oi? iluids for preventing,the deposit oi earbon in the engine eyliiulers.

Another objeet within the eenltenmlalion of the invention is to provide an apparatus of the character mentioned provided with controllable means whereby a, supply of heated air is introduced into the imini'l'old with the (.OlIllfllHiliOlkftlpilltlllllflgl' fluid, and whereby, upon throttling; said fluid, the heat supply is automatieally out all and a passage for the, introduction of cold air for cooling the cylinders is automatically opened.

With these and other objects in VlGW, the invention resides in the features of construetion,arrangement of parts and combinations of elements which will hereinafter be fully deseribed, reference, being had to the aecompanyiug drawings, in whichl igure l is a perspective view of the in-' vention;

Fig. 2 is a vertical section of the easing and associated parts; and

threaded upon the upper en '5'.

Fig. 3 is a view of said casinginhQI-iontal section.

'UNHED sm Parana onnion.

1 indicates a cylindrical easing having a ihreaded tubular stem 2 adapted for seating on the intake manifold 3 of an internal combustion engine. Removably mounted upon the. top of said easing is a cover or cap l whieh has :uljustahly mounted therein a centrally disposed vertical. tube 5 the lower end of 'which is shaped to'form a. spray nozzle 6 which approaehes the upper end of lhe passage through the stem :3. Leading into said tube 5 at oppositely disposed points above the casing are. two pipes 7 and S, of whieh the former is an oil supply pipe leading from a small oil reservoir 9, and the latter is a water supply pipe leading from a. small water reservoir 10.

A pin 11 with a needle point constitutes a valve 11. is disposed within the tube 5 nd which is adapted for adjustment withrespeel' to the nozzle passage for controlling the passage of the mixed oil and water dolivered to said tube through said pipes 7 and 8. Said pin has a fixed head '12 whieh is provided on its under side with av cam faee, as indicated at 13; and rotatable on said pin in underlying, relation to said head is a collar ll whose upper face corresponds to that of the engaging face 13 of the pin head 19. Said'eollar 15L is seated upon the upper end of an adjustin hat or sleeve 15 whichloosely embraces the r in lland is oi 'ihTagtube A eoil compression sprin 1 disposed in encircling relation to suit pin has its.

lower end seated upon a. fixed collar 17 carried by said pin and its upper end seated against the pin-embracing{portion 'orsaid adjusting nut 15, the same being designed to maintain the pin depressed with its head in yielding close-seating relation to the collar 14 and also to maintain the latter seated upon said adjusting nut. lllovement of the pin to and from chasing relation to the nozaie ti is accomplished in a manner which will hereinafter be explained.

Disposed within the casing 1 is n. eloia fitting rotary valve 18 of hollow cylinder shape which is adapted for rotarv movement with respect to the latter. Rigidly attached to said valve is an arm 19 which projects outward through a horizontal slot 20 of appropriate length provided in the cylindrical Wall of the casing. Said arm has pivotally connected thereto one end of an operating lever 21 whereby rotary movement may be imparted to said valve.

Provided in the valve 18 is a port 22 which is adapted to be carried into and out of register with the passage 23 of a horizontally disposed tubular stem 2d carried by the casing 1, said stem having connected thereto one 8I1d-0f a flexible tube 25 leading from a suitable heated air source, as a radiation box or casing on the exhaust manifold (not shown). The collar 14 and arm 19 are rigidly connected by means of an angular member 26, so that both will be actuated together, or simultaneously. Thus, movement designed'to shut 0d the fluid supply through the nozzle 6 also ciits oil the heated air supply, and vice versa.

Also provided in the valve 18 at a suitable point is a port 27 designed to be brought into register with a passage 28 provided in the casing 1 for the admission of cold air, said port 27 and passage 28'being so located relatively with respect to the aforementioned port 22 and passage 23 that the former can be placed in register only when the latter are out of register, and vice versa, or when the passage of fluids through the nozzle 6 is cut ofl.

As is obvious, the admission of heated air is designed to facilitate the gasification of the spray of oil and water as the mixture joins with the fuel mixture entering the manifold from the carburetor (not shown). It is further apparent that when cold air is admitted to the manifold, as described, for mixing with the'fuel mixture entering from the carburetor, the mixture furnished to the engine cylinders is rendered less eflicient, resulting in a slowing down of the engine speed and a consequent braking of the speed of the vehiclewhich is propelled by the engine a result which is particularly desirable, as when the vehicle is coasting down hill; Further, the admission of the cold air results in a desirable cooling of the engine eyl indcrs.

In practice, the nut or sleeve 15 is adjusted to regulate the relative positions of the valves 11. and 18, after which a lock nut 25) is threaded up thereagainst, as shown in Fig. 2. Stop cocks 30 and 31 provided, respectively, in the oi l. and water lines 7 and 8 are opened to admit the fluids to the tube The passage of said lluids through the nozzle 6 is then controlled by shifting movement of the lever 21, which, as hereinliefore explained, simultaneously,controls the admission of heated air. 3",

1. In a device of the character described, a casing in open communication with the intake manifold of an internal combustion engine, a valve forcontrolling the admission of fuel to saidcasing, valve-controlled means for introducing heated air to said casing, and means for opening and closing said fuel and hot-air valves, said casing hav- 7 5 ing a passage through which cold air is admitted thereto, said passage being opened simultaneously with the closing of said fuel and hot-air valves, and vice versa.
